Buying a used Apexi NEO

I haven't used an AFC before, and I have some general questions.
I don't think that they classify as "noob" questions, as I've read the sticky's and whatever recent posts that I could find.

When buying a used AFC (For example the NEO), can you "Flash/Reset" the unit somehow to erase all of the settings that the previous owner had input. For example, if I found a NEO on a Honda forum, is there anything that should stop me from buying used from another make of vehicle?

Also, would other makes have spliced into different wires on the unit, and if so will this affect the setup of the unit on a Maxima?

Any opinions for running the LC-1 w/ XD-16 & SSI-4 with the NEO?
This way I can tune against rpm easily with datalogging + "real time" readout.

Although this would be an expensive setup.......

I bought my SAFCII used came off of a supra. When I first hooked it up there were no settings on it but I belive you can reset them if not.

I have noticed a common question in the stickies and in some of the other threads that I have read on here about the number of tuning points on the NEO. Numerous members have asked whether the advertised 16 point resolution actually means 16 Hi and 16 Lo = 32 Points (Like the VAFC II 12 Hi + 12 Lo = 24 Points) or if it really mean 16 total points. After reading the manual, it seems to me that there are 32 total points . Just a heads-up to anyone scanning these threads.

I do have a question about wiring a Z32 MAF into a 5th Gen. On Pg 32 of the Apexi Manual, it says this:

For“Hot Wire”and“Pressure”, a sensor number in“IN”and one in“OUT”can separately be set.
Select the same value unless the airflow sensor is changed to another.


Does this mean that I can run the Z32 MAF, and select the "IN" on the NEO to correspond to the Z32 while selecting the "OUT" on the Neo to correspond to the 5th Gen MAF. This would take the signal from the Z32, convert it into an actual % on the NEO, then back into the correct signal to feed the 5th Gen ECU output.

Would this take care of the compatibility/wiring issues, or does the signal also lead elsewhere and cause problems?

You would need to re-wire that MAF even more so than a 4th genner has to. So, no, it would not take care of any of that/those wiring issue(s).

Bringing the thread back to life.

I did buy a used NEO, and now it's time to install.
I haven't found any wiring diagrams on this site for the NEO, and the supplied wiring diagrams don't include the Maxima in their list of Nissan vehicle diagrams.

Can anybody help me out with this?

You have the pinout for the connector from the Neo, correct?

I have the NEO Manual, so everything should be in that I would imagine.
I'm out of town at the parents house for the weekend, so I don't actually have it with me to check.

So assuming that I have the pinout in the NEO manual, if I could find the ECU pinout on here, then I could just match up the connections right?

Although if any of you have existing documentation from your install's, it would be a lot more fool-proof....

It's hosted on VQpower.com in the "How-to" section. Look for E-manage Ultimate installation guide.
